Electrodiagnostic (EDX) Medicine is a specialized area of medicine used to evaluate how well nerves and muscles are functioning. It relies on advanced neurophysiological testing (primarily Nerve Conduction Studies (NCS) and Electromyography (EMG)) to help diagnose conditions that affect the nervous system and muscles.
EDX testing is commonly used to identify problems such as carpal tunnel syndrome, peripheral neuropathy, pinched or injured nerves, and nerve-related conditions affecting the neck or lower back. By measuring the electrical activity of nerves and muscles, these tests can accurately determine the source of symptoms like pain, numbness, tingling, or muscle weakness.
Results from EMG and NCS testing provide valuable insight that helps physicians confirm a diagnosis and develop an effective, personalized treatment plan. Electrodiagnostic studies are performed by specially trained physicians in neurology or physical medicine and rehabilitation (PM&R).
